The First Helicopter Medevac Missions
In June 1945 the campaign to liberate the Philippines from Japanese occupation was underway and three of the Liberty ships were deployed to Luzon with the Fifth Air Force while the other three Liberty ships were deployed to the Marianas to support B-29 Superfortress operations with the Twentieth Air Force. On 15 June, R-4 pilot Louis Carle received a request to pick up two soldiers with head injuries 35 miles east of Manila. With only 25 hours of helicopter time and no medical training, Carle arrived at the designated spot but they couldn't locate the two soldiers needing evacuation. Men at the scene who greeted Carle had him fly out a platoon leader with a hip injury instead but they couldn't fit the stretcher into the R-4. Carle ended up removing the other seat and laying the injured soldier on the floor.
News traveled throughout the area of the successful helicopter evacuation and soon Carle and the other pilots of the repair ships were getting requests for additional medevac flights. Given the primitive state of helicopter technology of the day, the flights into combat zones were grueling and often the six pilots were flying as many as six to seven medevac missions a day. Often the pick up points were near front line areas and the helicopters were attractive targets to Japanese units. Mortar and artillery rounds often impacted near the landing zones as well, and adding to the stresses, the pilots were the only crew aboard and they had to load the injured, make sure they were secured, and then fly their flimsy machines out of the combat zone to a field hospital near Manila. As the American forces pushed into the highlands of Luzon, performance of the R-4 and later R-6 helicopters suffered and often Carle and his men had to overspeed the piston engines to get enough rotor lift to get airborne, all while avoiding enemy gunfire.
Carle and another pilot survived crashes of their respective R-4s after ten days. Both men were escorted out of the jungle highlands by appreciative Army units. With his repair ship heading to Okinawa to support the combat effort there, Carle would be officially credited with 12 saved soldiers though the actual numbers were likely quite higher. To replace the departing ship, another repair depot anchored in Manila Bay on 25 June and the four pilots aboard managed to medevac 40 injured soldiers in just four days. To make the medevac flights more comfortable for the wounded soldiers, the helicopter mechanics welded Stokes litters (steel tube and wire mesh baskets for carrying wounded) to the steel frames of the R-4 helicopters.
Of all the injured servicemen flown out of harm's way by helicopter in the Pacific Theater, 60 percent of those medevac flights took place on Luzon in that six week period. One-hundred fifty men are estimated to have been flown out and while this small number is nearly insignificant compared to the 40,000 saved by medevac flights in Korea and 1 million saved in Vietnam, the history making flights of Louis Carle and his fellow pilots in their flimsy Sikorsky R-4s convinced a skeptical military command of the value of the helicopter.
